Referring; to thevarious v-iews my invention-isg generally, designated l2 and consists of a windbw" frame designated l El secured adj 'ac'ent'a ledge l-"4 iin an opening provi'd'ed therefor-- in a: building structure; Thesaid window frame I3 is pro-- vided with an interior enclosure consisting of elements I'5' and' t6- and anupper frame element not numer-lcally designated and? a lower element des sections; being respectively secured to a casement windows Zili by means: of screws: 32 and 35; The lower arm or leg 33 is prefrably-ofiflaficonstructioni. as indicated in: Figure-7m The hinge element 3.6; is: provided with: a tubular" bearing portion 3'!" in. whichiaarighir. singularly benttrod 383is; articulatelysecuredi by virtue of' its: shorter extension; 39;.v its longer extension 41] being secured, to atnbular; pivotah element: 42 by:' means of a pin M. The: tubular: pivotal: element: 42 is provided withs-anextensionl 4ft which op'erates' in abea-ring 45 andaisflfirmlwlieldiirrplaceibyrivets-w ing or peening, the; head thereof as:.indicated. at; 46, a washer 41 being providedrifon smooth-.op:-=- oration; Ontheextension: 43- is; articulately mounted a bracket. element. 48.- having a: bifiuncated downwardly depending; extension. 48 which) rides on the leg or-arm 33 of"thefpiyotaltsupportelement; 26.

ItLwill banoted thatnthehinge elements. 322 and: 35'. are; suitably; offset in. order: to; permitt maximum range of opening which is somewhat 3 substantially more than 90 degrees from the normal of those positions indicated in Figures 7, 9, 10 and 11.

The means for operating the window to open position or closed position from within is made possible by the worm gear mechanism which is clearly illustrated in Figures and 6, wherein it will be noted that an arm 44 is articulately connected to the'extension 43 heretofore mentioned, and has provided at its opposite end a sectional worm gear 51, the said arm 44 being also pivotally mounted on a fulcrum 58 supported The by bearing portions 58 in a housing 53. housing 53 is also provided with a flange extension 5| with holes for receiving screws 52 for attaching the same firmly in place. The housing 53 is provided with bores 50 in which a worm 54 is rotatably confined, the said worm 54 having a blind square central opening 55 which is adapted to be engaged by a crank handle 59, so that the same when motivated clockwise or counterclockwise will cause the lever or arm 44 to either open or close the window. The forward portion of the handle 59 is also square as indicated at 60 in order to engage the worm 54 and impart rotation thereto whenever the handle 59 is motivated.

Referring to the window structure, it is also to be noted; that on element [5 I secure a cleat 24 so as to act as a finishing off for the interior of the extension of the window within a building and also to act as an abutment or stop for the casement window 2 0. V

The casementwindow 20 has a window pane 22 therein having an interior surface 23 and an outer surface 2L, The object of the mechanism provided is to permit motivating the window 20 so that the surface 21 will be accessible from the interior of the building as indicated in Figure 4. The frame I3 is provided with a recessed opening 62 therein to permit edges 63 of the window to abut thereagainst when the window is closed, the cleat 24 aiding in forming aweather seal with the window 20. The element l6 has an overlapping portion 25 by virtue of its being cut out at I! so as to overlap the mechanism which imparts articulate motivation to the-casement window.

It will be noted that the mechanism provided may be utilized to set the casement window 20 in any angular position within the maximum range of adjustment from the normal to the extreme open position. The important advantage .of opening the window in the manner indicated is that it facilitates cleaning of the window pane 22 on both sides without it being necessary to clean the outer surface of the window from the outside of a building.

It goes without saying that the operation or tion and passage of air currents into and out of a room in which the window i situated.

In actual operation or transition from the closed position shown in Figure 1 to the open position shown in Figure when the handle 59 engages the worm 54, causing the lever 44 to be rotatedoutwardly simultaneously therewith, the lever Which is articulately secured through the tubular pivotal element 42and the bent rod 38to 4 the extension 36, will cause the bracket element 48 to engage slidably by virtue of its bifurcation 49 the arm 33 and slide thereupon in order to permit the tubular pivotal element 42 to fold over inwardly, bend over, or overlap, as indicated in Figure 4. In like manner, as illustrated in Figures 10 and 11, the upper arm 29 will also simultaneously cause the hinge element 3| to overlap the same as indicated in Figure 11, when the window is open as shown in Figure 4, so as to maintain the window in rigid and fixed open arrangement. Because of the particular structural organization; of the worm wheel and worm gear construction as well as the hinge structure and the articulate and sliding bracket element 48, the said functions are possible. .Although I have herein described rather succinctly the nature and use of my invention so that persons skilled in the art will have no diificulty apprising themselves of the teaching thereof and, inasmuch as;the disclosure is susceptible of various a1terations,'modifications and improvements,

I hereby reserve the right to all modifications, alterations and improvements falling within the scope and spirit of my invention, as well as any modifications that are embraced suggestively in the accompanying drawings, and any that may come Within the purview of the foregoing description; my invention to be limited only by the appended claims.
